N-{[3-(4-tert-butylphenyl)-1,2-oxazol-4-yl]methyl}-5-chloro-6-ethylpyrimidin-4-amine CAS 866042-43-5

Description

The occurrence of N-{[3-(4-tert-butylphenyl)-1,2-oxazol-4-yl]methyl}-5-chloro-6-ethylpyrimidin-4-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-{[3-(4-tert-butylphenyl)-1,2-oxazol-4-yl]methyl}-5-chloro-6-ethylpyrimidin-4-amine (CAS 866042-43-5), a certified reference material (molecular formula C20H23ClN4O, MW 370.88 g/mol) for analytical method development and quality control.

N-{[3-(4-tert-butylphenyl)-1,2-oxazol-4-yl]methyl}-5-chloro-6-ethylpyrimidin-4-amine (C20H23ClN4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
